4AFTE / 7AFTE owner, need your assist, Something wrong with my setup. Options

[normality78]

Alright, i've been pm some members here who is having either 4AFTE / 7AFTE setup here to find out what is their power numbers they able to achieve. As i suspected there is a some flaw on my setup which i cant hit as impressive power figure as those bros here even almost similar setup.

Im trying to find out what wrong with my setup? On the dyno day, the only problem found was there was a leaking at the joint session between turbo manifold flange to turbo flange. But im skeptical that problem will cause me lost alot of power. Pls correct me if im wrong.

now im thinking to fully rebuilt my turbokit or i can do something on it. Thought of changing turbo and having some turbo choice in my head but i'll start another thread on that.

All negative and positive feedback/opinion/suggestion welcome.

Below is my recent dyno result.


Current setup was:
custom made turbo manifold
IHI RHB52
2.5" downpipe
2.2" from downpipe to dummy CAT
2" frm DUmmy CAT till straight flow muffler
2.5" s/steel pipe to IC
2.5" s/steel pipping frm IC thn having reducer to 2" s/steel pipping to TB
some ebay IC (590 x 230 x 67)


This is my turbo manifold.

holy crap, am i reading this right? 19.83 torque.... the flow on that turbo blows btw.
whens your boost kick in ?
ur running a little lean in the lower rpms if it kicks in around 3k....
but you're A/F looks good... with almost pushing 15psi u should've been hitting around 200+
i dont think its the turbo at all.
your clutch is going im thinking, no big flaws in the performance aspect.

hm.... my boost started to build around 2800rpm onwards i believe. cant confirm but will check it out again. yeah, i did notice my A/F does show lean on lower rpm but not sure why.

i've been running 15psi for 2 years now. I also suspect there is some sliping at gearbox.
